Wreck of Japanese wartime submarine found

Divers have found the wreck of a Japanese midget submarine that attacked Sydney Harbour in 1942 and brought World War Two to Australia's biggest city, ending a 64-year mystery over its fate.

The missing two-man submarine M24 was one of a trio that slipped in darkness past protective nets stretched across the harbour entrance on May 31, 1942, with a plan to attack shipping, including the American battle cruiser USS Chicago.

Two of the 46-tonne subs were sunk. But the M24 fired two torpedoes, one of which sank the converted ferry HMAS Kuttabul, killing 19 Australian sailors and two Britons before vanishing under heavy fire. The other torpedo failed to explode.
